 The 2026 JEL review, [Difference-in-Differences Designs: A Practitioner’s Guide](https://doi.org/10.1257/jel.20251650), is a strong starting point for the DiD framework. It organizes the literature around 2x2 building blocks, target parameters, weights, covariates, staggered adoption, and presents a "forward-engineering" approach.
